Collaboration is pivotal for any successful release. Can you imagine going through a sprint without consulting or informing any other team involved in the project about what you did? You can’t right because it is not a pretty picture. Modern SDLCs demand various teams to coordinate as they try to deliver a product as quickly as possible in the market, with assured quality.
A developer will always write code keeping different scenarios in mind but there could be cases where the implementation does not work as expected. The same principle also applies to test code that is primarily written to test the existing product functionalities, unearth bugs, and make the product 100% bug free.
When you start your journey as an automation tester, then mistakes are bound to happen. They may also happen if you are up in a race to automated website testing without exploring the impact of your Selenium test automation scripts in depth. And while it is good to learn from your mistakes, it is always better to be preventive by learning from others.
JavaScript is criticized as a language that is quite difficult to debug. It doesn’t matter how perfect the code of a front-end application is, some of its functionality will get impacted especially when we get down to test it’s compatbility across different browsers. The errors occur mostly because many times developers use modern Web API or ECMA 6 scripts in their codes that are not yet browser compatible even in some most popular browser versions. In this article, we will look at the errors commonly faced by developers in their front-end application and how to minimize or get rid of them.
